After the development of a first prototype, whose performance was presented at the SPIE conference on Astronomical Telescopes held last year in Marseille (Frontera et al. 2008), we have improved the lens assembling technology. We present the development status of the new lens prototype that is on the way to be assembled.","authors_text":"A. Basili, C. Guidorzi, E. Caroli, E. Virgilli, F. Evangelisti, F. Ferrari, F.
